GREEN College of Education Michigan State University East Lansing, MI  \nand  \nJOANNA MIRECKI MILLUNCHICK Materials Science and Engineering University of Michigan Ann Arbor, MI  \nABSTRACT  \nIn large lecture courses, it can be challenging for instructors to address student misconceptions, supplement background knowledge, and identify ways to motivate the various interests of all students during the allotted class time. Instructors can harness instructional technology such as screencasts, recordings that capture audio narration along with computer screen images, to supplement the lecture with content that addresses the diversity in student academic backgrounds, motivations, and interests, to extend the classroom experience, and reach the individualized needs of students. This study documents the strategic use of screencasts in a large introductory Materials Science and Engineering (MSE) course, and examines their impact on student usage and course performance. To assess the efficacy of screencasts, students were surveyed to determine how they used screencasts and whether they perceived these resources to be helpful. In addition, we correlated student usage based on website hits with student performance ([e.g. final](e.g. final) grade) to determine statistical significance. Since the course is comprised of students from different academic and social backgrounds, we also analyzed usage and performance patterns for particular student subgroups. The results indicate that students perceive the screencasts to be helpful and tend to use the resources as a study supplement. Overall, usage of screencasting in its various forms is positively and significantly correlated with course performance as indicated by the final grade. The most substantial gains were found for students with the least amount of prior exposure to concepts in the course material.

Screencasting has been successfully implemented as a training tool for task-centered activities in a variety of contexts [1–3] . Screencasts have been used to record and replay PowerPoint lectures and other training materials, but any application—including animations or drawing programs—may be captured along with audio commentary, then posted on a course management website and replayed at students’ leisure. Used properly, this approach can be a rich supplementary resource. It includes written, audio, and video elements, thus reaching students with many different learning preferences. Screencasts may be fast-forwarded, rewound and paused as necessary, and are available “on demand” and accessible to students at any time of day (in contrast to office hours, live chats, etc. ) . Our implementation of the screencast creates a flash movie that can be accessed through the course management website, but students may also elect to subscribe to the screencast via iTunes, allowing students to watch them on any mp3 player. The production of screencasts is extremely simple thanks to powerful software packages now available that range in both price and capability [4] .  \nLITERATURE REVIEW  \nInstructors are using audio and visual podcasts or screen","cbCaibA9mM7hgrVh","https://ap.wps.com/l/cbCaibA9mM7hgrVh","pdf",3311157,28,"English","# Abstract\n# Background\n# Literature Review","[{\"question\":\"What problem does the study address in large lecture courses?\",\"answer\":\"It targets the difficulty instructors face when addressing misconceptions, supplementing background knowledge, and motivating students with diverse needs within limited class time.\"},{\"question\":\"How were screencasts used and evaluated in the course?\",\"answer\":\"Screencasts were provided as supplementary resources, and students were surveyed about usage and perceived helpfulness.
